WILLIAMS CULVER, OF VINELAND, NEW JERSEY.

Letters Patent No. 99,065, dated January 25, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom. it may concern Be it known that I, WILLIAMS CULvER, of Vineland, in the county of Cumberland, and State of- New Jersey', have invented a new and improved Combined Innching and shearing-Machine; and do hereby declare that the following is a full, clear, and exact descrip'tion of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which the figure is a side elevation, the upper part of the frame ,being broken away, in order to show the eccentric lever-head bearing on the punch.

' This invention relates to a lever, pivoted in the upper part of a frame, and provided with a blade that works against a stationary blade in the frame, the two blades, together forming an apparatus adapted to shearing metal, the s'aid lever bearing an eccentric at its lower end, which works a punch, operated by the same' motion of the level' that-works the shearing-apparatus, an adjustable hed-plate being placed beneath the frame, and provided with one or more oriiices, either of which may be placed directly beneath the punch.

In the drawings- A is the frame, and B, the lever, the latter being furnished with a blade, b, near its pivoted end, which blade works against a blade, b1, fixed in the frame; the blade b being placed where the lever may be most powerfully exercised upon it.

On the lower end of the lever is au eccentric head, b2, which, as the lever moves up and down, operates a vertically-moving punch, O, placed in a guideway of the frame A.

A spring-plate, c`,vwho`se ends are sustained in projections cc 'on the inner side of frame, stretches across tbelintermediate space, and bearing against a shoulder ofthe punch O, tends to keep the latter elevated.

A bed-plate, D, rendered adjustable by slots near its ends, through which pass set-screws, fastening it to the base of the frame A, is provided with one or more vertical orifices, d, tted to receive the nozzle oi' the punch, one of which orifices should always be placed `directly beneath the nozzle.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

The improved machine herein described, consisting of the lever B, blades b b1, frame. A, punch C, spring c, and adjustable bed-plate D, al1 constructed and arranged to operate substantially as described.

To the above specification of my invention, I have signed my hand, this 7th day of December, 1869.

WILLIAMS GULVER.
